Hey folks I'm looking for a little help. I've gotten new bulbs for my driving lights and I'm giong to replace the wiring. I am putting in 100w H3 bulbs.

The plan is 12 guage for the wirre throughout the wiring. With a 30 amp fuse.

If I am correct with these bulbs I am drawing 15.6 amps with these lights on. Will this set-up be sufficent?

I am currrently wired directly through the battery with a toggle, but I'd like to add a new fuse panel for aux items. could someone reccomend what I should use. For aux Items I currently have driving lights and back-up lights. I would like to add some 4 more lights and an Aux. 12v port in the bed.

Last question I believe I have a 75amp alternator, would a 90 amp alternator be sufficent for my needs?

Thanks for any and all answers. JD

You need to use a relay for those lights. You can use a heavy duty switch but just do it the right way and run a relay.
